His professional career was intimately connected with Sporting de Gijón, which he represented for 15 years.
Born in Sotrondio, Asturias, Cundi spent his professional career almost entirely with local powerhouse Sporting de Gijón, save for a one-year loan spell with Unión Deportiva Poblense due to compulsory military service.
From the age of 20 onwards he was an undisputed starter for the La Liga side, appearing in nearly 400 official games during his 15-year spell: in the 1986–87 season, Cundi played 41 matches (3,549 minutes) for an eventual fourth-place finish; he did not receive one single red card during his career.
Cundi earned nine caps for the Spanish national team in two 1/2 years, being selected for UEFA Euro 1980. His debut came on 4 October 1978 in a Euro 1980 qualifier against Yugoslavia (1–2 loss, in Zagreb).
Cundi's son, Rubén, is also a footballer. An attacking midfielder he also made his grooming at Sporting de Gijón, playing six seasons with the first-team in Segunda División, where he would play most of his career for two other clubs.
